Solution 1 - Ruby on-Rails-3
You can also get the string, like "Wednesday", using time.strftime("%A")
Solution 2 - Ruby on-Rails-3
Can't you use time.wday, 0 = sunday and so on
Solution 3 - Ruby on-Rails-3
Actively using in Rails 4 - should in most other versions as well...
Both of these options will give you the day string (eg. "Saturday") for the date specified:
Specific date:
Date.new(2011, 1, 1).strftime('%A') # returns "Saturday"
Today:
Date.today.strftime('%A')
Solution 4 - Ruby on-Rails-3
If you're attempting to write your own calendar from scratch and want to write a function to do day lookup, you might want to check out Conway's Doomsday Algorithm, which is an interesting method for determining the day of the week on any given date. Otherwise the standard time class has a wday method which returns a number from 0-6 (0 is Sunday, 1 is Monday, etc).
Solution 5 - Ruby on-Rails-3
We can use Time.now.utc.wday to get day of week without considering zone.
Solution 6 - Ruby on-Rails-3
No need to use the Time class. date.cwday will return 1 for Monday, 2 for Tuesday etc.
